ERIE ODELL, OF ERIE, PENNSYLVANIA.

CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 430,399, dated June 17,1890.

Application filed August 5, 1889. Serial No. 320,326. (No model.)

To all whom it may concern:

Be it known that I, ERIE ODELL, of the city of Erie, in the county ofErie and State of Pennsylvania, have invented new and usefulImprovements in Carpet-Stretchers, of which the following is aspecification.

This invention relates to carpet-stretchers; and it consists in certainimprovements in the construction of the same, as will be hereinafterfully set forth, and pointed out in the perspective View of thegrappling-plate turned bottom side up. Fig. 5 is a perspective view ofone of the teeth on the grappling-plate. Fig. 6 is a top view of one ofthe teeth.

The device consists of grappling-knee pad, a spiked lever, and a chainor other flexible connection between the lever and the pad.

I am aware that carpet-stretchers have been heretofore made having aknee-pad for engaging the carpet, a spiked lever, and a connectionbetween the lever and the pad, and I shall not claim these elementaryparts or the combination thereof as my invention.

My invention consists in improvements in the construction ofcarpet-stretchers such as just described.

My improved carpet-stretcher is constructed as follows:

E is the lever, F the ferrule, and G the spike at the end of the lever.

D is a chain, which connects the lever E with the knee-pad at O. Theknee-pad consists of an iron frame 0, having an inwardlyprojectingflange N on its lower side; a sheetmetal plate K, which is pressed intoform to fit within and rest upon the flange N, and is provided withteeth, which are formed from the metal of the plate K by a punch or die;a backing block A, which sets Within the frame 0 and on the flange N andover the plate K, and, finally, a cushion B i, which is mounted on theblock A. The parts contained within the frame 0 are held in place bynails or screws h, which are inserted through holes in the frame 0.

The teeth formed on the plate K constitute an essential part of myinvention. They are formed by a punch or die, which cuts a V- shapedhole P in the metal, leaving the triangular fragment attached at itsbase, and its point or apex turned up from the plate at an angle theretoof about forty or forty-five degrees. The punch or die is so formed thatit not only cuts or forms the V-shaped tooth, but it also turns it up atan angle to the plate, and also forms a ridge or rib on the back of thetooth from point to base, said rib being wide at the base anddiminishing to the point of the tooth. This rib gives the tooth an archorA form in cross-section. This rib is marked M in Fig. 5. Teeth thusformed are very strong and will not bend back under any strain that canbe put upon them in ordinary use.

WVhat I claim as new is A grappling-plate for carpet-stretchers,consisting of asheet of metal stamped into proper form and havingtriangular teeth with longitudinal strengthening arches M, Which arewider at the base of the tooth and taper to its point, formed thereon bya die or punch, substantially asset forth.

WVitness my hand this 24th day of July, A. .D. 1889.

ERIE ODELL.
